Improvement in design of chassis and transmission system of a four wheel electric scooter for handicap

Abstract

This report aims to model, simulate, perform the static and dynamic analysis of a four wheel electric scooter chassis consisting of square and rectangular beams. modeling and simulation are performed using modeling software that is AUTODESK INVENTOR and analysis on ANSYS. The maximum deflection is determined by performing static analysis and dynamic analysis. As we had to customize scooter so it can be use for indoor and outdoor purpose both. Keeping that into mind we had design our chassis. Strength and light weight were our basic consideration through out the design of electric scooter. Hence, AISI1018 was selected as an appropriate material fir design which is medium carbon steel with properties such as light weight, height tensile strength, higher machine ability, better weld ability etc. All the impact and stresses were calculated manually by considering the severe working condition and then the design was analyzed on the software. After the complete and the approval of design by inspecting it in all the modes of failure type design was finalized.
